Cool man, thanks for posting it. I wish it would have focused more on the unique builds you can catch a glimpse of in the video, as opposed to being a taco commercial.
Still though, pretty cool and thanks for posting it.
I'm doing with my boys exactly as was stated in that video... trying to balance their computer/game time with outdoor/organic things. Such as camping, hiking, going to the beach, etc., and of course... building mini bikes and karts.
Good stuff.
